Abstract: A mount or submersible or semisubmersible housing for supporting a submersible analyzer or device and method for analyzing fluid. The mount includes an elongated submersible housing that supports the analyzer or device. The housing is ruggedized and has a geometric body with an internal cavity and with upper and lower ends. The upper end is configured to mount to a fixed structure. In some embodiments a slot extends between the upper and lower ends of the housing along a longitudinal axis thereof. In some such embodiments the slot is sized to receive a portion of a sliding extension that supports a sensor of the analyzer or device, thereby facilitating the installation and removal of the analyzer or device with respect to the elongated submersible housing. An attachment may be used to fixedly mount the elongated submersible housing to the fixed structure.
